Question

我想转移到名为DetailView的nib文件，而不是发出警报。我无法弄清楚如何使这个工作。我想把我的行数据带到新的Wiew。我真的试图让它发挥作用，但我无法弄明白。

您是否为DetailView的NIB创建了一个UIViewController？如果是这样，那么在UIViewController中创建一些属性来保存您的数据以推入新视图。确保您分配新的视图控制器并在IB中的笔尖视图控制器中设置所有必要的连接和委托。

然后实例化你调用UIAlertView的新UIViewController。

UIViewController *myVC = [[UIViewController alloc] init];
id myValueOne = [myDataOne objectAtIndex:indexPath.row];
id myValueTwo = [myDataTwo objectAtIndex:indexPath.row];
myVC.propertyOne = myValueOne;
myVC.propertyTwo = myValueTwo;
[self.navigationController pushViewController:myVC animated:YES];

希望这有帮助。
